The present application discloses systems, methods, and articles of manufacture for determining prescription rules for a hearing prosthesis. A system in accordance with the present disclosure includes a receiver, a transmitter for wirelessly inducing electrical signals in the receiver, and first and second loads coupled to the receiver and associated with first and second applications, respectively. The system also includes a signal generator coupled to the transmitter. The signal generator is configured to energize the transmitter to transfer the electrical signals at a first duty cycle to the receiver for the first application and to energize the transmitter to transfer the electrical signals at a second duty cycle to the receiver for the second application.
